/*
Package updatecontroller contains a controller that coordinates the
upgrade of clusters. It watches the cluster.Spec.Version and will
initiate the controlled update of first the apiserver, then the rest
of the control plane and finally nodes. It does so by manipulating
the ClusterStatus, letting other controller take care of reconciling
the cluster namespace or updating/watching the nodes in the user cluster.
